HOLDDOWN FOR STORAGE BATTERIES.

Application filed April 12, 1913.

present invention to provide a device for this purpose which will occupy comparatively little space and be cheap to make, and adjustable and readily applied and removed in use.

Another object of the invention is to provide a holddown for storage batteries which, by reason of its construction and operation, can be adopted by manufacturers of electric vehicles and the like as a standard for use in connection with storage batteries instead of each manufacturer rcsorting to some more or less unsatisfactory expedient of his own for this purpose.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment chosen from other embodimentsof it for illustration in the accompanying drawings in which- Figure Lisa-side view of a battery box held to its support by hold-downs embodying features of the invention. Fig. 2, is a view drawn to an enlarged scale and illustrating, partly in section, the upper portion 0f the hold-down. Fig. 3, is a view, partly in section, illustrating the hold-down prin cipally in elevation, and Figs. 4 and 5, are sectional plan views illustrating details of construction. 1

In the drawings 1 is a bifurcated claw which may be a stampingand it is adaptedfor attachment toa battery support 2. The battery support 2 may be the floor of a battery chamber such as is u ually provided in electric vehicles and the like, and the claw may be attached either to the top or bottom of the battery support 2, although it is shown as attached to the top ol the support in the drawings.

i, is a transversely perforated pintle turnable in the claw l and having its opening l located in the bifurcation of the claw.

5, is a rod penetrating the opening 4 in the pintle and having screw and thread connection therewith. This rod 5 is arranged Specification of Letters Patent.

in the bifurcation of the claw and at its upper end is provided with an eye (3. The.

support- 2 may be provided with an opening 7 for the acconiinodation of the rod 8, is a grooved disk turnable in the eye'O.. and provided with a handle 9 and witlraneccentrically arranged headed-pin It), the eccentric together with the pin and handle may be cast in one piece.

11, is a hook member having a :spring shank l2 perforated at 13 for the detachable reception of the headed-pin 10. Thishook nien'iber engages the top of the wall of the batterybox H and is marginally notched as at 15 for engagement with theshanks ofp the handle it a stamping.

The parts consisting as they do principally of castings and stampings and rods or pieces of bar metal are com|iaratively easily and cheaply manufactured. Furthermore. the hold-down can be readily applied to the battery support as by means of bolts 17 and the parts of the hold-down can be readily assembled. 7 i

In use the hook member 11 cannot slip off the top of the battery box because the notches 1:) engaging the shanks of the handle it; prevent such an accident, yet the hook members can be readily applied to different battery boxes and for this purpose they can be detached, ifdesired, by moving the pin 10 out of engagement with the opening l(. \djustinents can be. made b v screwing the rods 5 through the pintles 3 or unscrewing them since. these parts constitute what ma be called a turn-buckie and when desired and when the pins 10 are disconnected from the hook members these rod can be swung out of the way so that the mechanism is in eli eet a hinge turn-buckle. .\l'ter the proper adjustments have been aeconiplishial all that /it is necessary to do in order to clamp the battery box is to turn the disks by means of the handles 5) until the pins ill have. slightly passed the line of the centers of the disks and until the handles 1) are. seated on the rods lnorder that the pressure may not be too great the spring shanks ol' the. hook members are provided and by yielding. these spring shanks permit of the proper alinenientof the pin it) with the rentcrol the disk. lividently the hold-down occupies etnnparatively little space which is, ol course, advantageous.

It will be obvious to those skilled in the art that modifications may be made in de- The book membermay be but Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a hold-down device the combination of a claw, apintletm'nable in the claw and provided with a threaded opening, a threaded hold-down rod engaging the threaded opening in the 'pintle, and clamping means connected with the free end of the rod.

2. A hold-down for storage battery boxes comprising the COlTllJlllutlUll of a claw. a plntle turnable in the claw and provided with an opening, a rod arranged through i the opening in the pintle and having an eye,

a grooved disk turnable in the eye and provided with an eccentric headed-pin, and a hook member connected with the pin, sul' stantially as described.

3. Ahold-down for storage battery boxes comprising the combination of a claw, a pintle turnable in the claw and provided with an opening, a rod arranged through the opening in the pintle and having an eye, a grooved disk turnable in the eye and provided with an eccentric headed-pin, and a hook member detachabl connected with the pin. substantially as described.

4. A holddown for storage battery boxes comprising the combination of a claw member consisting of a bifurcated metal stamping, a transversely perforated pintle turnable in the claw. a rod penetrating the opening in the pintle and having a screw-andthread connection therewith and arranged in the bifurcation of the claw and having at one end an eve, a grooved di k turnable in the eve and provided with a handle and with an eccentric headed-pin, and a hook member consisting of a stamping having a spring shank perforated for the reception of the headed-pin and having marginal notches, substantially as described.-

In testimony whereof I have hereunto signed my name.
